EPD Device Scan for Router

Initial scan: EPD device scans each available channel. If the EPD device still

can't find the router after 2 mins, it will change the status to "lost connection".
Reconfirm scan: The device will start to scan the channel to look for another

router every 2 mins. If a device still can't find the router after 5 attempts, it will re-
scan the channel every 4, 8, 16, 32 mins, then every 64 mins for 5 days. Finally
the device will move to deep sleep mode after scanning for 5 days continuously.
Stop scanning and deep sleep: If the EPD device still can't find the router, it

will stop RF Scanning and go back to deep sleep mode until the button of the
device has been pressed. The device will start scanning from the beginning.
